Online Published on 14 February, 2024. Abstract Nutrient-and water-use-efficiency are the two drivers of improved citrus production. The experiment was conducted at Hatla village of Katol, Nagpur (Maharashtra) on ten- years- old Nagpur mandarin (Citrus reticulata Blanco) orchard under high density planting (6 m x 3m) during year 2021-2022. As many five levels of fertigation treatments viz., 85, 100, 115, 130 and 145% of recommended dose NPK of fertilizers were tested through randomized block design with four replications through eighteen splits application . The number of fruits/ plant was observed highest under fertigation with 145% of RDF (314.25 fruits/ plant), at par with fertigation at 130% of RDF (304.50 fruits/plant). Whereas, fertigation with 145% of RDF recorded highest average weight of fruit (171.98 g) , at par with fertigation with 130 % of RDF (170.30 g). The highest fruit yield (54.03 kg/ plant and 29.98 tons/ ha) was observed via treatment fertigation with 145% RDF. The superior fruit quality parameters such as juice content (51.77%), TSS (11.030brix), brix acid ratio (13.49) and ascorbic acid (35.79 mg 100 /ml) were observed with 145% of RDF equivalent fertigation. All the physical parameters of fruit such as fruit diameter (6.66 cm), peel weight (20.46 g), peel thickness (2.80 mm) and volume of fruit (155.63 m3) were registered higher with fertigation at145% of RDF.
